Handheld 3D Scanner Brings 3D Printing to the Masses
3D scanners collect real-world data about the shape and appearance of objects and people, and are typically classified as either contact or non-contact.
The earliest digital 3D scanners, called contact probes, were developed in the 1980s. Users would have to physically touch the object they wanted to scan hundreds or thousands of times with the instrument in order to collect enough data points to create a 3D model of the object.
Since then, 3D scanning has evolved using optical technology. Laser scanners, white light scanners, industrial CT, and LIDAR are some of the most prevalent forms of 3D scanning to date, and because this form of technology is still so young, many new innovations in this field are expected over the coming decades.
